Initial results in mice could lead to new way to fight neurodegenerative diseases
There’s new hope in the fight against Huntington’s disease. A group of researchers that includes scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice.
The compound is a synthetic antioxidant that targets mitochondria, an organelle within cells that serves as a cell’s power plant. Oxidative damage to mitochondria is implicated in many neurodegenerative diseases including Alzheimer’s, Parkinson’s, and Huntington’s. (more…)
UD doctoral student studies ways to improve lithium battery performance
Lithium batteries are used in many devices such as cell phones, computers and cameras, among others.
University of Delaware doctoral student Wei-Fan Kuan is investigating ways to improve membranes used in lithium batteries by capitalizing on the innate properties of block copolymers.
It is work that he believes will become increasingly important as the components in electronic devices continue to get smaller. (more…)
MU researcher finds that prostate tumor cells are more susceptible to treatment after being exposed to resveratrol, a compound found in grape skins and red wine.
Resveratrol, a compound found commonly in grape skins and red wine, has been shown to have several beneficial effects on human health, including cardiovascular health and stroke prevention. Now, a University of Missouri researcher has discovered that the compound can make prostate tumor cells more susceptible to radiation treatment, increasing the chances of a full recovery from all types of prostate cancer, including aggressive tumors.
“Other studies have noted that resveratrol made tumor cells more susceptible to chemotherapy, and we wanted to see if it had the same effect for radiation therapy,” said Michael Nicholl, an assistant professor of surgical oncology in the MU School of Medicine. “We found that when exposed to the compound, the tumor cells were more susceptible to radiation treatment, but that the effect was greater than just treating with both compounds separately.” (more…)
ANN ARBOR — The fossilized fangs of saber-toothed cats hold clues to how the extinct mammals shared space and food with other large predators 9 million years ago.
Led by the University of Michigan and the Museo Nacional de Ciencias Naturales in Madrid, a team of paleontologists has analyzed the tooth enamel of two species of saber-toothed cats and a bear dog unearthed in geological pits near Madrid. Bear dogs, also extinct, had dog-like teeth and a bear-like body and gait. (more…)
Doctoral student studies energy poverty in Ghana, Africa
In the United States, electricity is a creature comfort many citizens take for granted. Yet for more than a billion people across the globe, particularly in developing regions, electrification is the exception, not the norm.
Sub-Saharan Africa, for example, is the least electrified region in the world. It has the lowest generation capacity behind eastern South Asia and few programs that provide access to modern forms of energy. (more…)
Bryan Carter, a UA assistant professor of Africana studies, is among faculty members in the arts and humanities more readily employing consumer-based technologies in educational, creative, interdisciplinary and engaging ways.
Take a guess – what are the most common uses for devices like smartphones?
Earlier this year, the UK-based mobile network O2 reported that, on average, people use their smartphones to access the Internet, communicate via social media and listen to music. Other popular uses, as explained by an article in The Telegraph, include playing games and making phone calls. (more…)
Sequencing the barley genome will sow many benefits
Some 10,000 years ago, people found they didn’t have to live as nomads, hunting and gathering all their food. In the Fertile Crescent, they started planting crops.
The Fertile Crescent extended from the Nile Valley and along the eastern Mediterranean Coast, through the Tigris and Euphrates valleys of Mesopotamia and down to the Persian Gulf. There, the foundation crops of the Western World were first domesticated.(more…)
What is the basic concept behind “This is Not Civil Rights”?
The book examines more than 1,000 citizen complaint letters regarding rights from the late years of the Great Depression along with replies written by federal government officials. Looking at what people complained about, and how they tried to justify their claims, reveals how popular understandings of rights and the role of government develop over time. (more…)
